App opportunity

I downloaded an app - Merlin - which take in bird song and respond with the name of the bird.  I used it on the Cooriedog walk and was impressed.  The app recognised chaffinches (a lot), robins, Eurasain siskins and bullfinches.  I saw none of them.
At one point a car passed.  But the app didn't tell me the make or model.  At another, a plane flew overhead.  But the app didn't tell me its destination.  It seems there's an opportunity for someone.  Just putting it out there.
